Embodiment approach

[0031] In a specific embodiment, the second mesh network node detects the reception of the surrounding mesh network node by receiving the beacon frame of the surrounding mesh network node, or the second mesh network node sends a probe request frame Signal Strength (Received Signal Strength, RSS), so as to discover the first mesh network node that has passed the authentication, and send a first access authentication request message to the first mesh network node with the first mesh network node as the authenticator.

[0032]S12. After receiving the first access authentication request message, the first mesh network node uses a private key to encrypt the certificate of the first mesh network node and the first access authentication request message together to generate a first certificate Authentication request message, and sent to the authentication server;

[0033] S13. After receiving the first certificate authentication request message, the authentication server uses the publ...

Abstract

The invention discloses an access authentication method for a wireless mesh network. In the method, a second mesh network node finds out a first mesh network node passing authentication by detecting a node signal existing peripherally, takes the peer-to-peer first mesh network node as an authenticator and sends an access request to the authenticator; and the peer-to-peer authentication among Mesh equipment is realized through ternary authentication among the authenticator, a requestor and an authentication server, and the requestor accesses to Mesh through the authenticator. By adopting the embodiment of the invention, a conflict problem between bidirectional authentication between the mesh network nodes, and MKD (Mesh Key Distributor) logic can be solved.

Description

technical field [0001] The invention relates to the technical field of wireless mesh networks, in particular to an access authentication method of a wireless mesh network. Background technique [0002] Wireless Mesh network (also known as wireless mesh network) technology is a new type of wireless mobile communication technology for IP-based access, suitable for regional environmental coverage and broadband high-speed wireless access. Each node in a wireless mesh network can send and receive signals, and each node can communicate directly with one or more peer nodes. Each network node is connected in a wireless multi-hop manner through other adjacent network nodes, which can greatly increase the coverage of the wireless system. [0003] The wireless Mesh network includes four logical network devices, which are Mesh Point (MP), Mesh Access Point (MAP), and Mesh Point with a Portal , MPP) and user terminals (Station, STA). The wireless Mesh network architecture defined in 8...
